REVOLVER.

SPECIFICATION forming part of Letters Patent No. 561,963, dated .Tune16,'1896. application filed May 2,1s9a. Serial to. 547,s45. (No model.)

' To all whom it may concern.-

Be it known that I, HOMER M; CALDWELL, a citizen of the United States, residing at \Vorcester, in the county of oreester and State of Massachusetts, have invented a new and useful Improvement in Revolvers, of which the following, together with the-accompanying drawings, is a specification suflh ciently full, clear, and exact to enable persons skilled in the art to which this invention appertains to make and usethe same.

The object of my present invention is to {provide a revolver-frame formed with solid line of the frame.

conceals the hammer,

cheeks and having a top opening to facilitate machining or cutting out the interior of the frame for the reception of the lockwork, and also provided with a conveniently-removable top cap that bridges over said opening and the two sides'of the capforming parts of the opposite side surfaces and secured to the frame as mprc fully described.

' Another object is to provide a revolver with a frame having a top openingfitted along its upper edges with shoulders or offsets formed on a circular contour, in combination with a top cap having its edges fitted to rest upon and match said shoulders, whereby the cap is supported against lateral looseness and in proper elevation above the hammer.

Another object is to provide a hammer having its face provided with two contact-ears adapted to strike the seat or frame at either side of the firing-pin, and to render the hammer-top low in position, thus permitting the top covering-cap to be formed below the top I attain these objects by a revolver mechanism constructed as hereinafter explained in detail, and shown in the drawings, wherein- Figure l is a side view of a revolver embracing my invention. Fig. 2 is a transverse section at line X X. Fig. 3 is a longitudinal vertical section with the top cap removed. Fig. 4 is a horizontal section showing the top of the frame and hammer. Fig. 5 shows a longitudinal section and front endview of, the cap, and Fig. 6 shows the side and front of the hammer.

Referring to parts, A denotes the frame, B the barrel, and C the cylinder, relatively disposed in the usual manner. and having combined therewith suitable or well-known means for effecting rotation of the cylinder, opening and closing the arm, ejecting emp y shells, and such devices as are usually ems ployed in revolvers, which will be fully un derst-ood, but not being features of my present invention need not be herein particularly described.- 1

In accordance with this invention the frame A is made with solid cheeks or sides a and with a top opening E, through which convenient access is afforded for machining and fitting the interior'of the frame for the hammer-seat and reception of the lockwork, which latter is preferably of the form shown in Fig. 3. The top of the frame is best cut away at both sides in uniform opposite rela-' tion, and preferably on the line of a circular curve,-as at 3, the edges fitted with an inward ofiset or shoulder 4 and upwardly-projecting lip 5, extending fromthe top of the frame 9 to the rear part 10 thereof, as indicated. Combined with this open-top cutaway frame I provide a removable top cap F, that bridges over and closes the opening, said cap corresponding in width to the lateral width of the frame and extending from theunder side of the barrel latch-bar B to the position 10 in rear of the-hammer H.

The top 6 of thecap' is arched to cover the hammer-head in its line of movement, and the sides f f are disposed flush with theisides a of the frame. (See Fig. 2.) The lower edges 7 are dressed oif on a circular curve and reduced to form the lip 8, that matches the curved edges frame, over and upon which the edges of the. cap fit and rest, while the ends of the cap fit the frame at 9 and 10, respectively, thus af fording a complete closui'e and finish for the top of the frame, concealing the hammer, and showing a neat and smoothpxterior surface at the sides. I i I Small pins 11 and 1 2,arranged through'holes in the lip 8 and frame at the upper and lower ends of the cap, serve for retaining the cap securely in position, or, if in any instance preferred, other suitable fastening devices nay be used in lieu of said pins.

Byforming the frame as shown with the edges 3 and 4 on the line of a circular arc, the construction and the process in manufacture are greatly facilitated and simplified in labor and machining operations, and the accurate fitting of the frame and cap to each other is rendered practically simple and rapid; also, by forming the edges to intermatch in the manner specified perfect fit and support for the cap laterally is attained, so that the opposite outer faces on the dependent sides f of the top cap and the outer surfaces of the framecheek are maintained positively flush or in proper relation to each other.

The hammer H is arranged in the top opening and pivoted, as usual, between the cheeks, as at r. This hammer H, according to my improvement, is formed broader than usual and with a low rounded top, as at m, Fig. 6,

and provided with a bifurcated strikiug-face,'

that presents two coritact-ears or forwardlyprojecting side portions h, that strike the hammer-seat e at the right and left of the firingpin head 15, and with an intervening space or vertical recess I between said ears it, that receives, without touching, the firing pin 1 5 when insnormal condition of inaction, and

ployed with the top m on line with or below the upper part of the firing-pin thereby faci l i tating the use of alow top cap F for coneealing the hammer and closing the top of the frame without extending the cap above the bottom line of the barrel-strap B.

It will be understood that the idea of in terposing the end of'a lifter between a hammer face and firing-pin as a means for giving projectivemovement to the latter isnot, broadly,

a feature included as part of the present invention, since this invention. relates to the improved structure of the parts in comhina tion, as defined.

I claim as my invention and desire to scmre by Letters Patent 1. The revolverirame formed as descril NIL-(l1 with solid checks, cut away at the upper part and having a top opening through which the hammer can be introduced and a, removable top cap fitting over and closing thehamnieropening; said cap composed of an archedtop portion, the full Width of the frame, with two integral, downwardly-extending opposite side portions, as shown, that match the respective cheeks, and form parts of the two side faces of the frame, as set forth.

2. In a revolver, thef ram 9 formed with the solid parallel cheek portions, and provided with a central hammer-space opening in'its t0p,a'nd having the upper edges of said cheeks, adjacent to said opening, cut away on the line of an inward circular arc, and fitted,a long such circular arc, with shoulders or hearinglips, as shown; in combination with the re-. movable top cap bridging over said opening above the hammer-space, and extending; rearword from the under side of the barrel latchbar to a position in rear of the hammer, the two sides of said top cap depending to form parts of the parallel cheek-surfaces, and fitted with circular curved edges that match the circular edges on the frame-cheekaand suitable pi us or fasten mg devices for securing; said cap to the frame, substantially as set forth.

3. In a revolver, ti combination. of the frame having solid side cheeks and open top, the low-topped hammer pivoted. in the opening between said cheeks, its face provided with projecting contact-cars and an intervening recess, the top cap hridgingand covering the ll&llll!i( lf,i ides flush wi 1d supported upon the check 5 ei te yrs of the frame, the firing-pin fitted in the frame, the trigger, and thehammor-actual oar having an ex: tended. end adapt tc'rpeq-ziiion -within the hammer-far: r GOl'i'tZtCl; with the firing-pin, all s tani'i y as set forth.

Witness my hand this 39th day of April,
